This invention relates toa lifting jack de-1 able the replacing of springs, or for any other purpose. 1 Further objects of the invention are to provide, in a manner as hereinafter setforth, a lifting jack which is simple 1n construct1on.

and arrangement, strong, durable, compact, thoroughly eflicient in its use, of a size capable of being stored in the vehicle when not in usefconveniently operated, readily assembled and comparatively inexpensive to manufacture. i

With the foregoing and other objectsin View the invention consists of the novel construction, combination and arrangement of parts as hereinafter more speclfically described, and illustrated in the accompanylng drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be had which will fall within' the scope of theclaimshereunto appended.

In the drawings wherein like reference characters denote. correspondingparts throughout the several views Figure 1 is a sideelevation of a lifting g 1 portand arealso welded to the coupling jack in accordance with this invention.

Figure 2 is an elevation looking toward: the front thereof. Figure 3 is a front elevation, partly in sec-' tion.

Figure 4: is a side elevation partly in' section and illustrating the device in operative position with respect to the axle of a motor vehicle and with the axle lifted by the de-' vice.

A lifting invention, includes a base 1, preferably of rectangular contour and which is provided Each support includes a circular 0&Sl1'1g8" the upper ends of flange parts 1 1, 12.

jack, in accordance withthis flangepart IOand disposed substantially at. .right angles with respect to the lug 16, is 190 at its center with a socket'Q, opening at the upper face of the base. Positioned within the socket 2 is a standard or pedestal 3 of the desired height and formed with a socket 4 opening at the top edge of the standard. Arranged within the socket 4, projectingupwardly therefrom the desired distance is a coupling bar 5 which extends between and is fixed to a pair. of oppositely disposed: up-

wardly extending supports referred to'g'enerally at 6, 7.

. As the supports 6, 7 are of the same construction, but one will be described as the description of one willapply to the other.

opening'at its inner side and a triangular shaped carrier 9 for the casing 8. Each support is formed with an integral, inwardly extending, right angularly disposed. flange which is coextensive with. the sides and top of the support. The part of the flange, indicated at 10 is semi-circular. V The remaining parts of the flange, which are indicated. a at 11, 12 depend from the ends of part 10 at inward inclinations toward each other. The inner face of each support is formed with a semi-circular flange 13, which is oppositely disposed with respect to flange part 10 and merges into the ends of the latter and into The flange part 10 and flange, part 13 provide the annular body of the casing 8. The

part 14 of the support forms the outer'side wall of the casing ,8. The lower end portions of the flange parts 11, 12 of one support are welded, as at 15.- to the lower end portions of the flange parts 11, 12 of the other-sup- Formed integral withand disposed centrallyof the flange part'lO, at the top of the latter, is an upstanding, ap'erturedf lug 16 I which'is of a wldth corresponding to that of '95- flange partlO. The purpose of luglt) will be presently referred to. v V Formed integral wi h the outer face of ijecting, apertured lug'l'l', and, adjacent lug 17, flange part is cut away to'provide an 7 opening 18 for a purpose to bepresently referred to.

, The part id of each support, which provides the outer side wall of casing-18 is formed at" its centerwitli an opening 19 for a purpose to be presently referred to.

When the supports 6, 7 are set up, the "lower ends thereof are connected together-"'- and the upper ends spaced from each other,

but said upper ends are coupled together-by atie bolt 20 extending throughtheaperk tured lugs 16 and having' its head" 21 abut ting againstthe outer face of one lug-16 and" its other end projecting from the othenlug 16. and: carrying a securing'nut- 22 which abuts against the outer face of the-last mentione'dlug.--
